Flight of the Conchords, Tim Minchin and South Park creators Matt Stone and Trey Parker were named as possible headliners.

When asked whether they might stage a Blur vs Oasis-style rivalry with Flight of the Conchords, Black told Rolling Stone: "We actually have been talking about joining forces, because we've always wanted to do a double bill.

He continued: "You get your Tim Minchins. You get your Neil Hamburgers. You get your Tim and Erics. You take your Mr Shows - they've got incredible songs. Get your dudes from South Park, Matt and Trey.
